Hi, does anybody know how to realize this circuit?

Thanx for answers. But what should I do when I need to regulate current at some constant voltage? For example for charging of accumulators ... sometimes I need 3.6V and 180 mA, sometimes 3.6V and 1.8 A. Should I build project http://www.electronics-lab.com/projects/power/011/index.html or is it still the same as this psu?

Hi! I have built this psu, but when I connect some load to it and I set voltage to some value and then I decerase current (by setting current limit), voltage decerases too. Has it to be so?
